The thermocouple is an sesnsing device , when the temperature increases it increases the voltage , that voltage is used for tripping purpose
YesYou should be careful with power cables nearby and make sure they are shieldedwww.peaksensors.co.uk
You must use thermocouple wire (of the same type as the thermocouple) to extend the circuit. If you switch to a different wire the point of connection between the two becomes a thermocouple junction itself, and the resulting voltage from that junction will skew your reading. You can use any wire to extend a thermocouple connection if you know the temperature of the junction where the thermocouple wire ends--this becomes the reference junction.
The output of the thermocouple is linear.
No If you want to maintain reasonable accuracy you must use the correct type of compensating or extension cable to match the sensor. The accuracy of the system depends on all system components. The output is generated when the wires are in thermal gradients, so if there is any thermal gradient across the compensating/extension cable you will get errors if you do not use the correct type www.peaksensors.co.uk
The thermocouple which measured the car's coolant temperature failed and so the car overheated.

Compensating cable is required for thermocouples to maintain accuracy in temperature measurements by minimizing the effects of temperature variations along the length of the wiring. It ensures that the electrical characteristics of the cable are similar to those of the thermocouple, preventing erroneous voltage readings due to thermal gradients. Additionally, compensating cables help in extending the distance between the thermocouple and the measurement instrument while preserving the integrity of the temperature signal.

Yes, thermocouple is used in fridges !
To create a thermocouple one needs thermocouple wire, a means of spot welding the wire, and wire strippers. A thermocouple is used to measure temperature.
is a thermocouple an active or passive transducer?-why?
The thermocouple keeps a gas pilot light burning.
You should not paint a thermocouple.

To test a thermocouple on a water heater, you can use a multimeter to measure the voltage output. Disconnect the thermocouple from the control unit and place the multimeter probes on the thermocouple terminals. A functioning thermocouple should produce a voltage reading within the expected range. If the reading is outside this range, the thermocouple may need to be replaced.
Yes, it's an active transducer. A thermocouple is passive not active
